Hello, the control board on my Amana fridge used to fry, over an over, every 6 months or so.
I've heard from the technician about voltage spikes and how it affects all electronic componants
and he recommended that I purchase a surge protector designed for appliances from these guys Products and Accessories for Home and Appliances
Been 8 months now and the fridge runs smooth. Even had a few power outage and the board didn't flinch.
That little gizmo really does the trick. I pluged it in the outlet and it's ready to go.
Each repair on my fridge cost about 315$ so it's really worth the 13$ I paid for.
Max.
